Minimizing Residual Pulsation by Proper Dampener Installment

CONNECTION OPTIONS, For "Close Coupling" A small dampener of large diameter fitted close to a pump is better than a large dampener of small diameter fitted away from a pump. Keep the distance from dampener internals to pump internals less than 10 pipe diameters.

Standard for SoG & PeG units for low pressure & thin-wall pulsation dampeners. Aka "New England Style" - one up, and one in left field. One connection small for constant velocity to system and the other large for peak velocity from pump

Fits in place of a pipe spool. Length RF to RF normally 1.5 x dampener diameter. Connections are one large for pump peak velocity and one small for system constant velocity. Twin 90 x 90 with ANSI B16.5 flanges – AKA “Texas style – Bullhorn”

Food + Drug standards. Only available in “FDA” and chromatography “dampeners”. Widely spaced for full cross flow in place flushing

"BUILD YOUR OWN" CONNECTION SYSTEM.
UP TO 6 CONNECTION SOCKETS.

"Dampeners that do - flow goes through, pressure pulses do not"
2 connection (minimum) for in place flushing before service. Or if you only require flow fluctuation reduction, with no guarantee of pressure pulsation damping, then use the extra connection to save a "T" for the system RV, drain, or gauge.

SUCTION

In multi pump & multi head systems: pressure pulsation reduction level can be guaranteed by preventing interaction between pump head check valves and preventing resonance.

Close coupling ensures that the small mass of the liquid column is unable to excite the pump parts by going into oscillation. True thru-flow ensures that pressure fluctuations are captured and can not by-pass. Alternately, liquid mass that has to go up one hole, come to a halt, then reverse back out again in a fraction of a second, requires huge pressure fluctuations to produce this instantaneous mass reversal.
